GoKawiilGoogle links phone numbers across all signed-in accounts by default
Android includes a phone number verification setting that is enabled by default, which associates a user's phone number with every Google account signed into that device. Users must manually opt out if they do not want their number linked across accounts.
GoKawiil's interpretation of the reporting above, not reported fact.
Because the setting is opt-out rather than opt-in, many users may be unaware their phone number is being shared across multiple accounts, which could affect privacy for people who keep personal and work or secondary accounts separate. This raises questions about Google's default privacy posture and how clearly such settings are disclosed to users.
- The phone number verification setting on Android is enabled by default.
- It links a user's phone number across all Google accounts signed in on the device.
- Users need to actively find and disable the setting to opt out.
